prime number: numbers that only two factors, for example 29 1x29
2, 3, 5, 7, 11, 13, 17, 19, 23, 29
composite number: a number that has more than two factors, for example: 4, 6, 8, 9, 10 etc....
factor: numbers that you multiply to get a producet, for example 2*4=8, so the factors for 8 are 2 and 4
prime factorization: a number written as the product of its prime factors, for example 12 = 3 * 2 * 2
exponential notation: see above 12=3*2^2
Greatest Common Factor, GCF:the largest factor that a set of number have in common, for example: THe GCF of 45 and 60 is 15.
Numerator:the number on the top of a fraction Denominator:the number on the bottom of a fraction Reciprocal Property:a fraction multiplied by its reciprocal is always equal to 1, for example: 1/5 * 5/1 = 1
complementary angles: a pair of angles that add up to 90 degrees
supplementary angles: a pair of angles that add up to 180 degrees
interior angles: an angle that is inside a shape
exterior angles: an angle that is outside of a shape
adjacent angle: two angles that share a side and a point
vertical angle: two angles that are opposite eachother
acute triangle: a triangle that has all acute angles
obtuse triangle: a triangle with one obtuse angle
right triangle: a triangle with one right angle
equilateral triangle: a triangle with all sides and angles that are equal
isoceles triangle: a triangle with at least two congruent sides
scalene triangle: a triangle with no congruent sides or angles
parallelogram: a 4 sided figure with two sets of parallel sides, opposite angles are congruent
rhombus: a parallelogram with congruent sides
trapezoid: a quadrilateral with only one set of parallel sides
parallel: lines that are the same direction and the distance apart perpendicular: two lines that intersect to make a right angle, 90 degrees
